SOP's for the pongo's!! Brill in the summer, water fights etc. Not such fun after a winter ex, North German plain though.
We even do the tech standards cleans. Bulling rags at thirty paces with the duty grown up REME 'supervising' us from the uckers board.
Rite of passage IMHO. Except when I'm on engine bay cleaning duty (not a clean place on a Lynx!!)
